Abstract: Various aspects provide for receiving identity information from a station (STA) that identifies the STA as a sensor-type STA, determining whether communication attributes of the STA correlates with communication attributes expected for a sensor-type STA, and determining that the identity information received from the STA is false when the one or more communication attributes of the STA is uncorrelated with the one or more communication attributes expected for a sensor-type STA. Additional aspects provide for initiating one or more remedial actions upon determining that the identity information is false. The communication attributes may pertain to packet size, inter-arrival time, and/or inter-arrival time variance. The remedial actions may include blocking a future communication with the STA, communicating a warning message to the STA, and/or assigning the STA to a particular access window. Communications by the STA may comply with aspects of Institute of Electrical and Electronics Engineers (IEEE) 802.11ah.

Abstract: A user terminal for multiple-user wireless communication is provided, comprising a transmit buffer configured to store uplink data for transmission. The user terminal comprises a processor configured to generate a request to transmit frame in response to uplink data being present in the transmit buffer, and initiate a transmit timer for determining when to transmit the request to transmit frame. The user terminal comprises a transmitter configured to transmit the request to transmit frame when the transmit timer expires or when the uplink data present in the transmit buffer exceeds a threshold amount. The user terminal comprises a receiver configured to receive a clear to transmit frame from an access point based on the transmitted request to transmit frame. The transmitter is further configured to transmit the uplink data present in the transmit buffer, concurrently with at least one other user terminal transmitting uplink data, to the access point at a specified time based on receiving the clear to transmit frame addressed to the user terminal.

Abstract: Apparatus and method are provided for performing asynchronous discovery among multiple peers in a wireless peer-to-peer (P2P) network. In an aspect of the disclosure, a peer selects a duty cycle C corresponding to a probability that the peer is in either a scanning state or an advertising state, rather than a sleeping state, wherein the duty cycle C is selected in accordance with a power consumption of the peer. The peer also selects a first probability Pt for being in the advertising state, and performs an asynchronous discovery protocol in accordance with the duty cycle C and the first probability Pt.

Abstract: Methods, systems, and devices are described for wireless communication at a station. The station identifies a first set of enhanced distributed channel access (EDCA) parameters for a first access category based at least in part on a first traffic type and a determination that a multiple user (MU) frame is to be transmitted, and contends to gain access for a transmission opportunity over a shared radio frequency spectrum band to communicate with a plurality of other stations in a MU mode. The contention is based at least in part on the first set of EDCA parameters.

Abstract: Methods, systems, and devices are described for wireless communications. A network may employ additional contention based parameters to support MU transmissions and to communicate to other devices a duration that protects MU transmission. For example, a first device may transmit a first message to reserve a subband of shared spectrum. The first message may be addressed to multiple devices and may indicate a channel access deferral duration to other devices within transmission range. The non-addressed devices may refrain from accessing the channel for an indicated duration. The addressed devices that receive the first message may respond to the first message with a second message, which may also be used to reserve the channel. The second message may additionally be used to identify those devices that received the first message. The first device may generate a trigger message based on the received second messages.
